Hadith 192

Bulugh al-Maram

Book 7: Business Transactions
وَلِمُسْلِمٍ : { أَمْسِكُوا عَلَيْكُمْ أَمْوَالَكُمْ وَلَا تُفْسِدُوهَا , فَإِنَّهُ مَنْ أَعْمَرَ عُمْرَى فَهِيَ لِلَّذِي أُعْمِرَهَا حَياً وَمَيِّتًا، وَلِعَقِبِهِ } 1‏ .‏
Muslim has:

"Keep your properties for yourselves and do not squander them, for if anyone gives a life-tenancy it goes to the one to whom it is given, both during his life and after his death, and to his descendants."
